摘      要：Objective:To monitor iodized salt consumption and evaluate iodine deficiency status in 2014 in *** and Methods:In 2014,a nationwide cross-sectional survey was conducted in 31 provinces (in this study,provinces,autonomous regions and municipalities in China s Mainland were named as provinces).Probability proportional to size sampling method was adopted to recruit children ages 8-10 and pregnant women.47,467 children s and 18,994 pregnant women s urine samples were collected and 47,706 children s thyroid volumes were *** content in salt was determined with 46,900 edible salt samples from children s households;urinary iodine concentration (UIC) was tested from children and pregnant women s urine samples;thyroid volume of children was assessed by ***:The national coverage rate of iodized salt and consumption rate of qualified iodized salt were 96.3％ and 91.5％,*** iodine content in iodized salt was 25.2 mg/*** 22 of 31 provinces,the provincial coverage rates of iodized salt were over 95％.And consumption rates of qualified iodized salt were more than 90％ in 21 *** this study,the national median urinary iodine concentration (MUIC) of children in China was 197.9 μg/*** the provincial level,MUIC of children in 19 provinces was 100-199 μg/L,which in 12 provinces was 200-299 μg/*** national MUIC of pregnant women in 2014 was 154.6 μg/L,slightly higher than the lower limit of the WHO criteria for adequate (150-249 μg/L).At the provincial level,MUIC of pregnant women in 18 provinces was 100-149 μg/L,which in 13 provinces was 150-249 μg/*** national prevalence of goiter among children in 2014 was 2.6％,of which only Shandong province (5.6％) exceeded the national standard (5％).Conclusions:In China,iodine deficiency disorders (IDD) has been eliminated since *** in 2014,the IDD-free status still remained.
